The horizontal section top coal caving in steep seam is different from the gently inclined seam.

急斜煤層水平分段放頂煤開采與緩斜煤層不同,工作面沿煤層厚度的水平線布置,長度短。

It mostly study on the content of the relationship between support and surrounding rock in longwall top-coal caving mining of steep seam by using field observation, theory calculation, similar and numerical simulation.

本文結(jié)合新疆烏魯木齊礦區(qū)的實踐,利用現(xiàn)場實測、理論計算、相似模擬和數(shù)值模擬等手段,以急斜煤層綜放開采“支架-圍巖”相互作用關(guān)系為核心研究內(nèi)容,對急斜煤層綜放開采的工作面礦壓顯現(xiàn)規(guī)律、開采引起的上覆層結(jié)構(gòu)形式、頂煤冒落特點和支架合理結(jié)構(gòu)的分析等相關(guān)內(nèi)容全面地進(jìn)行了研究,取得了一些有創(chuàng)建性的研究成果。
